Finding a detailed beginners' crochet pattern that fits the desired design is the easiest way to start a simple slipper project. The pattern typically provides information about the best type of yarn for the design, along with the types of stitches needed and potential variations for sizing the slippers up or down. Buy yarn and crochet hooks appropriate for the yarn's weight. Follow the pattern's instructions to crochet the slippers and to add any optional embellishments.
Although the types of stitches and number of rows vary depending on the slipper style and size, nearly all crochet projects begin by making a slip knot to secure the hook and the yarn. Once the slip knot is tightened, chain the number of stitches specified in the pattern, along with additional stitches such as the single crochet or double crochet, to crochet the rows of the sides, soles, and instep of each slipper.
After crocheting the components of the slippers, join them together to finish each slipper. Arrange the instep on top of the sole with the sides wrapped around. Pin the pieces together, and sew the sole to the sides of the slipper before creating the heal seam, and joining the sides together. Fasten off, and weave the ends of the yarn into the heal seam. Sew embellishments such as crocheted flowers, or trim onto the slippers as desired.
